Microgrid Components. Like a traditional grid, energy generation is the heart of a microgrid system. This can range from diesel generators and batteries, the most common sources at the moment, to power generated by renewable resources such as solar panels, wind farms, fuel cells, or other sources of renewable energy.
A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a mission-critical site or building. A microgrid typically uses one or more kinds of distributed energy that produce power. In addition, many newer microgrids contain battery energy storage systems (BESSs), which, when paired
